Abstract

The invention relates to a drive control system of torsion fatigue test equipment. The drive controls system comprises an industrial control computer, and further comprises a servo drive, a servo motor, an encoder and an on-site module. The industrial control computer is connected with the on-site module and the servo drive, the on-site module is used to collect an acquired peripheral signal and output a control signal to peripheral equipment, the encoder is used to feed information of the servo motor back to the industrial control computer, the industrial control computer is used to perform calculation according to the peripheral signal and the information and output an operation result to the servo drive, the servo drive is used to drive the servo motor according to the operation result of the industrial control computer, and the servo motor is used to achieve drive of the torsion fatigue test equipment. The drive control system has a series of advantages of high control precision, small size, energy conservation, good durability and the like, and is advantageous in that a torsion angle is not limited.

Description

technical field [0001] The invention belongs to the technical field of control, and relates to a drive control system, in particular to a drive control system of torsional fatigue test equipment. Background technique [0002] The current torsional fatigue test equipment is typically driven by mechanical drive or hydraulic drive. [0003] Among them, the mechanical driving method adopts a mechanical cam or a four-bar linkage, which converts the rotation of the motor into yaw, and changes the size of the torsion angle through the cam track or adjusting the eccentric distance. However, the mechanical drive method has a narrow range of torsion angle (generally below ±40°), low test frequency (the mechanism operates in an unbalanced state, and the test frequency is generally below 10Hz), large vibration and noise, and cumbersome adjustment of torsion angle , Inconvenient operation and other disadvantages, it is suitable for places where the test accuracy is not high. [0004] T...
